Alpha
Description
Alpha
Usage
getAlpha(x)
Arguments
x
(data.frame) First column has to be year and following
columns contain species abundances.
Value
A data frame with results for S (species richness), N (numerical
abundance), maximum N per year per assemblage, Shannon, Exponential
Shannon, Simpson, Inverse Simpson, PIE (probability of intraspecific
encounter) and McNaughton's Dominance.
Examples
## Not run:
# 1 site, 1 year in long format, ordered by ABUNDANCE or BIOMASS
x <- data.frame(species = letters[1:6], x = 6:1)
getAlpha(x$x)
## End(Not run)
